Many thanks for the retweets and feedback on Part one of this blog

Here is Part Two
Here we extend the discussion and also suggest a practical (and open) way to create a way forward
To recap, lets keep in mind the big picture and after considering Streaming in the previous section, let us consider more techniques like Edge Processing etc
Many vendors like Cisco and Intel are proponents of Edge Processing (also called Edge computing). The main idea behind Edge Computing is to push processing away from the core and towards the Edge of the network. For IoT, that means pushing processing towards the sensors or a gateway. This enables data to be initially processed at the Edge device possibly enabling smaller datasets sent to the core. Devices at the Edge may not be continuously connected to the network. Hence, these devices may need a copy of the master data/reference data for processing in an offline format. Edge devices may also include other features like:
• Apply rules and workflow against that data
The concept of a Data Lake is similar to that of a Data warehouse or a Data Mart. In this context, we see a Data Lake as a repository for data from different IoT sources. A Data Lake is driven by the Hadoop platform. This means, Data in a Data lake is preserved in its raw format. Unlike a Data Warehouse, Data in a Data Lake is not pre-categorised. From an analytics perspective, Data Lakes are relevant in the following ways:
Some deep learning techniques could apply to IoT datasets. If you consider images and video as sensor data, then we could apply various convolutional neural network techniques to this data.
It gets more interesting when we consider RNNs(Recurrent Neural Networks) and Reinforcement learning. For example – Reinforcement learning and time series – Brandon Rohrer How to turn your house robot into a robot – Answering the challenge – a new reinforcement learning robot
Over time, we will see far more complex options – for example for Self driving cars and the use of Recurrent neural networks (mobile...
Some more interesting links for Deep Learning and IoT:
Systems level optimization and process level optimization for IoT is another complex area where we are doing work. Some links for this
Visualization is necessary for analytics in general and IoT analytics is no exception
Here are some links
NoSQL databases today offer a great way to implement IoT analytics. For instance,
In this section, I list some IoT technologies where we could implement analytics
We started off with the question: Which points could you apply analytics to the IoT ecosystem and what are the implications? But behind this work is a broader question: Could we formulate a methodology to solve Data Science for IoT problems? I am exploring this question as part of my teaching both online and at Oxford University along with Jean-Jacques Bernard.
Here is more on our thinking:
We started off with the question: At which points could you apply analytics to the IoT ecosystem and what are the implications? And extended this to a broader question: Could we formulate a methodology to solve Data Science for IoT problems? The above is comprehensive but not absolute. For example, you can implement deep learning algorithms on mobile devices (Qualcomm snapdragon machine learning development kit for mobile mo.... So, even as I write it, I can think of exceptions!
